• the actual cam 20a ends at both ends by a positioning surface 20b in which comes 7/24044 PCMB96 / 01459
• the control member 20 has a slot 20d on its external face adjacent to the face of the casing link 16 normally turned towards the arm of the wearer, to allow it to be maneuvered.
• Figures 1 and 3 illustrate the device with the fixing pins 18 protruding from the casing link 16, while Figures 2 and 4 show these same pins 18 in the retracted position in the housing 16.
• An advantage of this embodiment is to ensure positioning of the fixing pins 18 at the two ends of the cams 20a, that is to say in the two angular positions of the control member 20, preventing any accidental stalling of the bracelet.
• the control member 20 occupies a stable position, both when the fixing pins 18 are pushed outside the casing 16, as when they are retracted.
• the fixing device of the second embodiment comprises a casing 1 of cylindrical shape traversed longitudinally by an eccentric bore in which are driven two sockets 2 at the two respective ends, their bottoms 2a being adjacent at the respective ends of the casing 1. These bottoms 2a are each pierced with an opening 2b for the passage of a fixing dowel 3.
• the internal end of each dowel 3 ends in a head 3a and a coil spring 4 surrounds each pin 3 and bears at one end against the bearing formed by the head 3a and, at the other end, against the bottom 2a of the sleeve 2.
• the casing 1 also has two lateral openings 5 and 6 aligned on a transverse axis perpendicular to the longitudinal axis of the casing 1 and to that of the sockets 2, the opening 6 being of a larger diameter than the opening 5.
• L opening 6 is closed by a closure plate 7 with beveled edge, engaged in a corresponding bevel 8, formed around the opening 6 and held by a screw 9 with conical head pressing against the beveled edge of the closure plate 7.
• a control member 10 is slidably mounted along the transverse axis of the openings 5 and 6. It has a cylindrical part 10a, the diameter of which allows it to pass freely through the opening 5, followed by a conical part 10b , the diameter of the base allows it to move freely through the opening 6.
• This member 10 comprises a cylindrical housing 10c opening on the side of the base of the conical part 10b and in which a coil spring 11 is housed and supported, on the one hand at the bottom of this housing 10c, and on the other hand against the closure plate 7, thus pushing the control member 10 through the opening 5 until the conical part 10b abuts against the edge of the opening 5.
• the strap fixing end in the case of a leather strap or the like, has a part folded back on itself, thus forming a loop in which the casing 1 is introduced like a conventional bar.
• the bracelet 14 is pierced with a punched opening to give access to this member.
• the variant illustrated in Figures 7 to 10 is intended in particular to prevent accidental pressure on the pusher 10 does not allow the bracelet to come off. It comprises a casing 31 comprising a central part 31a constituted by a circular housing and two coaxial tubular parts 31b extending radially on either side of the central part 31a, driven into two diametrical openings thereof.
• the external ends of the tubular parts 31b each form a span 31 'b serving as a support for a return spring 32 wound in a helix around a sliding pin 33 whose internal end ends in a hemispherical head 34 forming a second span against which the other end of the spring 32 bears.
• the pins 33 are pressed against a conical cam 35b formed on the internal end of a push button 35, movable along an axis perpendicular to that of the pins 33.
• This push button 35 which, apart from the cam 35b, has a body of generally cylindrical shape, passes through an opening 37 formed through one of the end faces of the circular case constituting the central part 31a of the casing 31.
• a spring 36 bearing against the inner side of a cover 38 screwed into the circular housing 31a and constituting its second end face, elastically maintains the pusher 35 in the position illustrated by FIG. 7, the conical cam 35b serving to limit the travel of the push button 35.
• the cylindrical part of the push button 35 which normally projects out of the central part 31a of the casing, comprises two diametrically opposite stops 35c which project radially from the cylindrical surface of this push button 35
• the opening 37 in which this push button 35 slides has two diametrically opposite clearances 37a and dimensioned to allow the passage of the stops 35c. If the angular position of the stops 35c does not coincide with that of the clearances 37a, the push button cannot be pressed in the central box 31a, so that the pegs 33 cannot be retracted and the bracelet remains in place.
• stops 35c The purpose of these stops 35c is to prevent the involuntary disengagement of the pegs 33 from the horns of the watch, for example.
• Figure 11 illustrates a device similar to that of Figure 5, wherein the push button 10 'has a section other than circular, for example square. Even though this actuating member 10 ′ cannot rotate in the opening 40, it is possible to ensure that the length of the part which projects laterally out of the cylindrical casing is approximately equal to the thickness of the bracelet 41. In this way, it is not possible to accidentally actuate the pusher 10 ′ since it is necessary to bring it down below the level of the bracelet. Of course, it would also be possible to associate locking means with the pusher 10 '.
• this push button 10 'in Figure 11 may appear on the bottom or top of the bracelet. This remark also applies to the embodiment of Figures 1 to 4. In the latter case, it is possible to give the control member 10, 20 a decorative appearance, either by its shape itself, either by an added element.
• the device object of the invention has more particularly been described so far used for fixing a bracelet to a watch case, it is obvious that this device can be used for fixing any link to an object. , such as a strap to a bag or other leather goods for example.
• This device could also be used in jewelry, for example to join the two ends of a bracelet or a necklace, playing, in this case, the role of a clasp.
• the slot 21 could be replaced by a gripping member in relief appearing on the external face of the bracelet and making it possible to operate the control member to by hand, without the use of a tool.
• locking means associated with the pusher 35 have been shown, it would also be possible to associate locking means with the rotary control member 20 even though the risk of accidental actuation of this member is improbable. However, in the case where this member is designed to be actuated by hand, without the intermediary of a tool, as mentioned previously, such locking can be useful.
